Why ventilate your home?

The need for Ventilation systems are becoming prominent as people are looking at increasing the air tightness of their properties. By adding features such as extra insulation in the loft, cavity wall insulation, double glazing and in some cases even triple glazing, it's having a detrimental effect on the air quality within homes.

Problems can arise when there is no natural air flow through the building, and no way for damp, stale air to escape the property. This can lead to condensation on windows and mould growth which can be hazardous to you and your families health. 

At RB Central Vacuum & Ventilation Systems, we can offer a wide range of Ventilation products, which can provide the correct type of ventilation for your property and your budget. Below we've listed some of the Ventilation products we stock and use on our projects. If you would like to know more about Ventilation products and services get in touch

dMEV fans

By using a very low powered energy efficient dc motor dMEV fans run continually. The fan will continuously extract air within the room it has been fitted in, therefore there is no chance for damp stale air to encourage condensation or mould growth. 

These types of fans are ideal for bathrooms, wc’s, kitchens and utility rooms etc. The fan can be boosted via a switch/pull cord which will increase the speed, the dMEV's we use also have ramp technology allowing the fan speed to increase with the change of demand of the room.

Positive ventilation systems

Positive ventilation units (PIV) are a very sophisticated whole house ventilation and condensation control system that are designed to gently ventilate the building from a central position on the landing of the property.

The ventilation unit keeps a subtle air supply throughout the property to transform a stagnant stale atmosphere into a fresh healthy, condensation free home and with a very energy efficient heater, it can gently temper the air before supplying it into the property, if the outside air is cold during the winter months. By using a sensor the fan intelligently knows when to operate the heater depending on the outside temperature.

  • Stops streaming windows
  • Improves indoor air quality
  • Removes musty odours                                                                           
  • Built-in low energy heater warms incoming air
  • Eliminates condensation & mould growth

Single room heat recovery

We can supply and install single room heat recovery units, that can recover up to 75% of energy, which would normally be lost through traditional break out points within the building fabric, reducing carbon emissions.

These types of fans are ideal for WC's, utility rooms, kitchens & bathrooms, where there is a high heat and moisture content. we can either replace existing extract fans or offer new installations.


An Axco Mechanical Extract Ventilation (MEV) system uses background ventilators, usually trickle ventilators fitted in windows and a centrally located continuously running mechanical extract fan with ducts running from the moisture producing areas or "wet rooms" such as kitchens and bathrooms. The background ventilators provide the whole building ventilation and the central mechanical extract fan runs continuously to remove odours and excessive humidity.

 There is built in humidity tracking in all our MEV's, meaning your unit will automatically boost on demand but additional boosting can be controlled via boost switches/pull cord.
